JOSLTH A. FERRIS, OF NE'W YORK, N. Y.

WINDOW.

Application filed February 27, 1913.

To all whom t may concern.'

Be it known that l, Josnri-i A.. FERRIS, a citizen of the United States, and resident of VVoodhaven, in the county of Queens, city and State of New York, have invented certain new and useful improvements in Windows, of which the following is a specifica tion.

Ny invention relates to windows and has for its object to provide a construction which will insure a tight fit of the sashes and prevent them from rattling, and which will enable the lower sash, or both sashes, to be removed from the window frame without disturbing the parts of the window beyond loosening a movable portion of the jamb or stile, which also gives access to the sash weights.

A specilic example of my invention is shown in the accompanying drawings, in which- Figure 1 is a vertical section of the complete window, taken on the plane indicated by the line 1-1 of Figs. 3 and il; Fig. 2 is a section on the same plane, but with the sashes omitted; Fig. 3 is a vertical .section on line 3N?) of Fig. 2; Fig. l is a partial horizontal section on line Jl-fi of Fig. l; Figs. 5 and G are partial horizontal sections on lines 5 5 and 6 6 respectively of Fig. 1; Fig. 7 is a horizontal section on the same plane as Fig. 5, but showing the lower sash in position for removal; Figs. 8 and 9 are a partial top view and a partial side elevation of the two sashes; and Fig. 10 is a vertical section of a modification, taken on the same plane as Fig. 3.

The window frame proper comprises a i top 10, a sill 11, two uprights or sides 12,

and two jambe or stiles 13 spaced from the uprights to form the pockets l/ft which receive the usual sash weights and cords or chains (not shown). The sill 11 is provided in its upper surface with a transverse horizontal groove 11a and adjacent thereto, toward the outside of the window, with an upwardly extending transverse rib 11b. An ornamental frame 15, 15a may be provided. at the inside of the window, and another frame 16, 16, at the outside, these parts, 15, 15, 16, 16a, being of any suitable construction.

Each of the stiles 13 is made with a vertical groove 13a in the same plane with the groove 11a of the sill 11, and with another groove 13b which connects with a transverse Specification of Letters Patent.

serial no. 'maeva groove 10a provided in the under face of the top 10. A parting rib 13C, 131 extends between the two grooves 13a, 13b. @ne of the stiles has a removable portion 17, preferably made with ends beveled in the same direction, as shown best in Fig. 8. This portion is normally held in position by screws 18 the heads of which are readily accessible. The removable portion is set against correspondingly beveled surfaces of the ixed stile portion, and is provided with a groove 17a registering with the groove 13a, and virtually forming part thereof. The removable portion 17 is also made with a rib or ledge registering with the parting rib 13G, 13d. rllhe upper portion 17h of this rib is flush with the upper parting rib portion 13C, while the lower portion 17 is set back and flush with the lower parting rib portion 18d. The junction of the two portions 17h, 17c is steplilre as shown in Fig. 2, the lower surface 17 having an upward eX- tension 17d of about half the width of the parting rib. rlhe removable portion 17 is not the full width of the stile 13, but eX- tends outwardly only to the inner edge of the groove 13b, the latter therefore being continuous and not interrupted by the said removable portion. rlhe other stile 13 is made with a removable portion 19 which differs from the removable portion 17 only by having its ends beveled in opposite directions (see Fig. 3) instead of the same direction. Similar reference characters are ap plied to corresponding features of both re movable portions. The removable portion 19 is held by screws 20.

The upper sash 21 is provided with a transverse rib or flange 21a adapted to enter the groove 10a of the top 10, and the lower sash 22 has a similar transverse rib 22 adapted to enter the groove l1 of the sill 11. The sashes are also made with side ribs or beads 21h, 221 respectively adapted to slide in the grooves 13b and 13a, 17a respectively. The meeting rail 22 of the lower sash is narrower than the meeting rail 21 of the upper sash. The meeting rail 22C is adapted to slide between the surfaces 13C, 17h, 191 of the two stiles, while the meeting rail 21 is adapted to slide between the surfaces 13d, 17, 19c of the two Stiles. Fig. 3 shows clearly that the slideway for the meeting rail of the 'upper sash is wider than the slideway for the meeting rail of the lower sash. When the upper sash is fully raised,

its L-shaped meeting rail 21c fits against the two shoulders at the upper ends of the surfaces 17C, 19c ofthe removable portions 17 and 19 respectively. A tight joint is thus obtained at the overlapping meeting rails and also at the frame ends of the sashes.

rThe strip 19 is removable simply for the purpose of obtaining access to the sash weights on one side of the window. The strip 17 is removable for the same purpose, but in addition serves to allow the lower sash or both sashes if desired, to be removed with great ease. 1t will be noticed that the removable stile portion 1.7, and consequently, the opening left after removal of said portion, are wider and higher than each of the sashes, so that when brought into registry with such opening, the sash may be moved laterally so as to extend into one of the pockets 14, the other edge of the sash being thereby released from the window frame.

In detail, the operation ot removing and replacing the sashes is as follows: 1f with the sashes in the position illustrated by Fig. 1, it is desired to remove the lower sash 22, this sash is raised until the lower screws 18 are exposed and these lower screws are removed, then the upper screws 18 are removed and the stile portion 17 is pushed into the pocket 14 or taken out bodily. r1`he lower sash having been brought to a position in registry with the opening formed by the removal of the stile portion 17, and having been disconnected from the sash weights on both sides (in the well-known manner), is shifted laterally so that one of its edges will enter the open pocket 14, which will cause thev opposite edge of the sash to become disengaged from the guide grooves 13a, 19a. The sash can then be drawn inward at the disengagededge, as indicated in dotted lines in F ig. 7, and can then be removed fromv the window entirely by sliding it or pulling it in the direction indicated by the arrow. Of course, the opposite procedure is followed in replacing the sash, but it will be advisable to apply the lower screws 18 first, then lower the sash to the position shown in Fig. land then apply the upper screws. This presents the advantage of holding the stile portion 17 reasonably steady while the upper screws are being applied. 1n case, after removing the lower sash, it is desired to remove the upper sash also, the latter will be lowered until it is at the same level as the opening left by the removal of the stile portion 17. inasmuch as the parting rib portions 17", 17C, 171 have been removed together with the stile portion 17, the upper sash can then be pulled toward the inside of the window (at the same time turning the sash slightly about a vertical axis so as to disengage it from the parting rib on the other side of the window) and thus the upper sash is brought into registry with the opening left by the removal of the stile portion 17 and can be removed from the window in the same manner as described for the lower sash.. 1n replacing the upper sash, the same steps are performed in the reverse order. instead of beveling the ends of the removable stile portions 17 and 19, 1 may reduce them. in step-like fashion, as indicated in Fig. 10.

Various modifications may be made without departing from the nature oic my invention as set forth in the appended claims.

l claim:

1. 1n a window, sliding sashes provided with lateral guide ribs, and a frame having stiles each comprising a fixed portion provided with a continuous groove for guiding one of the sashes, with two longitudinallyalining spaced guide groove sections for the other sash, and with two longitudinallyalining spaced parting rib sections, and a removable portion having a guide groove section and a parting rib section interposed between the respective spaced sections of the fixed portion.

2. 1n a window, sliding sashes provided with lateral guide ribs, and a 'frame one stile of which comprises a fixed portion provided with a continuous guide groove for one of the sashes, with two longitudinally-alining spaced guide groove sections ttor the other sash, and with two longitudinally-alining spaced parting rib sections, and a removable portion of less width than the stile but of greater height and width than the sash, said removable portion being provided with a guide groove section and with a parting rib section interposed between the corresponding spaced sections of said fixed portion.

3. 1n a window, sliding upper and lower sashes provided with meeting rails, the meeting rail o1 the upper sash being L-shaped in cross section, and wider than that of the lower sash, and a frame having stiles provided with guides for said sashes, the lower lstile portions being oiiset relatively to the upper stile portions so that the space between the upper stile portions is narrower than that between the lower stile portions, the adjacent ends of said upper and lower portions overlapping in step-like fashion, corresponding to the L-shape of the said meeting rail et the upper sash, said meeting rail moving between the lower portions of the stiles, and being adapted to engage the shoulders formed by said overlapping ends of the upper and lower stile portions, while the narrow meeting rail of the lower sash moves between the upper stile portions.

4. 1n a window, sliding sashes provided with lateral guide ribs and with meeting rails of dilerent width, and a frame each stile of which comprises a, fixed portion provided with a continuous guide groove for one of the sashes, with two longitudinallyllt alining spaced guide groove sections for the other sash, and with two longitudinallyalining spaced parting rib sections, the lower parting rib sections being offset outwardly so that the distance between said lower parting rib sections, which receive the wide meeting rail between them, is greater than the distance between the upper parting rib sections, which receive the narrow meeting rail between them, and a removable portion having a guide groove section registering with the spaced alining guide groove sections oi the fixed stile portion, and also having a parting strip section the upper por` tit tion of which is Hush with the upper parting strip section of the Xed stile portion, while the lower portion of said removable parting strip section is offset outwardly and flush with the lower parting strip section of the fixed stile portion.

In testimony whereof l have signed this specification in the presence of two subscribing witnesses.
